The country had informed the International Atomic Energy Agency (IAEA) of its intent to continue enriching the uranium at 20%, IAEA spokesman Fredrik Dahl told CNN on Friday.
Iran currently enriches its uranium stockpile up to around 4.5%, which is above the 3.67% cap imposed by the 2015 nuclear deal, but far short of the 90% that is considered weapons-grade. Iran has continually denied its intent to assemble nuclear weapons.
Government spokesman Ali Rabiei said Monday that Iran started the enrichment process a “couple of hours ago” in the Fordow site, noting that the first UF6 enriched uranium will be produced in a few hours, IRNA said.
IRNA added, citing Rabiei, that all the necessary measures, such as informing the IAEA, have been taken.
Last month, Iran’s parliament overwhelmingly endorsed a draft bill aiming to counteract sanctions imposed on its nuclear program and boost uranium enrichment, state-run Press TV said.
“The law obliges the Atomic Energy Organization of Iran to produce at least 120 kg of 20% enriched uranium annually and store it inside the country,” the Mehr news agency reported.
